Last night my 20D suddenly stopped functioning. I could hear the mirror just slapping up and down. I turned the camera off and it still kept going. Removed the battery, which stopped the problem until I replaced the battery. Switched the battery and it still continued. I left the battery out overnight, but as soon as I inserted the battery abck into the camera (with the power off), the mirror slapped a few times. I turned the camera on and confirmed that none of the menus or other functions will operate. The top screen either shows a flashing empty battery (battery has just been recharged and registers fine in my 30D) or the dreaded ERR 99 message.
I'm planning to send it to the Canon service center on NJ for a repair estimate, but I am thinking a repair wouldn't be cost-effective. Has anyone else ever had this problem?
